My Mother was just diagnosed with AMD so I did some hunting. Officially there is no cure for AMD but I suspect that it is more correct to say there is no profitable cure for AMD. Red Light Therapy particularly at 670nm has shown a lot of evidence that it is helpful. Vitamin K also looks promising.
Anyone else have some thoughts on AMD
Photobiomodulation for the treatment of retinal diseases: a review
"Age-related macular degeneration
The first evidence for the application of PBM to treat AMD in humans became available in 2008 from a prospective study of 348 eyes of 203 patients where Ivandic and Ivandic[21] demonstrated improvement in visual acuity (VA) in patients with the dry and wet forms of AMD. Three hundred and twenty-eight eyes of 193 patients received four 40seconds-long transconjunctival irradiations over 2wk with 780 nm light from a semiconductor laser diode with 0.3 J/cm2 delivered in the macular region during each treatment, with no adverse effects. Among the treated eyes, 146 had cataracts while 182 did not. The remaining 20 eyes of 10 patients received mock treatments and served as controls. The primary outcome VA improved in 97% of the treated patients who had cataracts by a mean of 2 lines (range 1-7 lines) and in 94.5% of the cataract-free patients by the same amount, with no change in VA in the few remaining treated eyes or in the controls. The VA improvement was accompanied by a decrease in metamorphosias, scotomas, and acquired dyschromatopsia. Also, in the sub-population of patients with wet AMD, PBM treatment reduced the edema and bleeding. The only drawback of this study was the disproportionately small control arm.
Further support for PBM's usefulness in treating AMD patients stems from a prospective interventional case series of 18 eyes of 9 patients with dry AMD carried out by Merry G. et al, titled “Treatment of dry age-related macular degeneration with photobiomodulation” and presented at the 2012 ARVO Annual Meeting in Fort Lauderdale, FL. The PBM treatment there consisted of irradiation by the LED-based devices Warp 10 (Quantum Devices) at 670 nm, for 88s, delivering 4-7.7 J/cm2 and Gentlewaves (Light Bioscience) at 590 and 790 nm, for 35s, delivering 0.1 J/cm2 per treatment. All 18 eyes were treated sequentially with both devices each time for a total of 18 treatments (3 times per week for 6wk), with no adverse effects. There was statistically significant improvement in VA, by 1.5 lines on average, and in contrast sensitivity, with no changes on their third primary outcome-fixation stability."

Near-Infrared Light Heals Eyes
"Ms Albarracin said that treating the retina with just a few minutes exposure to soft near-infra-red light a day for less than a week had produced a remarkable recovery in damaged photoreceptors (vision cells) which ordinarily would have died."
